摘　　要：被动式低能耗技术是实现建筑节能和助力“双碳”目标实现的重要途径之一。对低能耗建筑进行合理的优化设计可以最大限度地发挥其节能潜力。夏热冬暖气候区的气候特点决定了低能耗技术在该地区建筑设计应用中的特殊性。为寻求适宜于夏热冬暖地区北区低能耗建筑的优化设计策略,以位于福州市的某低能耗建筑为研究对象,采用定性与定量相结合的研究方法,在定性提炼其所蕴含低能耗技术的基础上,利用Ecotect软件对围护结构的热工特性及自然通风强化设计两方面进行优化,提出了适宜于该地区低能耗建筑的热设计优化方案。研究成果可为当地低能耗建筑的热设计提供理论基础,亦可为该气候区低能耗建筑的应用推广提供技术支撑。Passive low-energy technology is one of the important ways to achieve building energy saving and help achieving the double carbon goal, and reasonable optimization of low-energy buildings can maximize their energy-saving potential. The climatic characteristics of the hot summer and warm winter climate zone determine the particularity of low-energy technology in the application of architectural design in the region. In order to seek an optimal design strategy suitable for low-energy buildings in the northern district of hot summer and warm winter, this paper takes a low-energy building located in Fuzhou City as the research object, adopts a combination of qualitative and quantitative research methods, and uses Ecotect on the basis of qualitatively refining the low-energy technology contained in it. The software optimizes the thermal characteristics of the enclosure and the enhances design of natural ventilation, and proposes a thermal design optimization scheme suitable for low-energy buildings in the area. The research results can provide a theoretical basis for the thermal design of local low-energy buildings, and can also provide technical support for the application and promotion of low-energy buildings in this climate zone.
